Abstract：
The aim of the study is to develop the strengthening approach that changes the structure with cantilevered gallery from single-span into double-span, which can provide the basis for the seismic strengthening on gallery type single-span frame. Based on incremental dynamic analysis method, study the damage and collapse margin ratio of structure reinforced with the approach that add columns to gallery of former frame, contrast to former structure. The results show that structure added columns picked by nonlinear static analysis is superior to the former structure on the damage and collapse margin ratio, with the same ground motion effect.
